It mainly consists of a long tubular furnace chamber, heating elements, a temperature control system, gas inlets and outlets, and a furnace body shell, etc. It is commonly used in processes such as heat treatment, sintering, annealing, chemical vapor deposition, and high-temperature reactions of materials.

[0003] The existing utility model with the authorized announcement number CN210773409U discloses a high-temperature combustion tube furnace. Through the combined action of the burner, combustion nozzle, heat transfer tube, and constant temperature chip, it is used to enhance the radiation heat transfer and fluid flow wall attachment effect at the lower part, maintain the stability and uniformity of the annular combustion nozzle, so as to improve the combustion environmental protection effect. By setting the steam discharge pipe, through hole, and heat sink, the heat dissipation effect is improved. Through the cooperation of the lifting workbench assembly, shock-absorbing base, and spring layer, it can be safely earthquake-resistant, making the adjustment flexible and achieving an integrated working effect. By using the set pressure gauge, temperature controller, and voltmeter, it is convenient to timely understand and control the temperature, so as to achieve the best energy-saving and environmental protection effect.

[0004] Adopting the above technical solution, although the combustion environmental protection effect, heat dissipation effect, and energy-saving and environmental protection effect are improved, in the above technical solution, tubular containers or guides such as test tubes often need to be placed from the outside to the inside in the tubular furnace chamber, lacking a reinforcement and stability structure for fixing the external tubular containers or guides, resulting in the tubular containers or guides at the tubular furnace chamber opening of the tube furnace being easily separated from the tube furnace due to inclination or accidental pulling force, so that the tubular containers or guides are easily dropped and broken.

[0005] Therefore, we propose a high-temperature combustion tube furnace to solve the above problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Refer to Figures 1-4, A high-temperature combustion tube furnace, comprising a tube furnace main body 1, a controller 2 is arranged on the outer side of the tube furnace main body 1, connecting frames 3 are arranged on both sides of the tube furnace main body 1, and two fastening bolts 4 are jointly threadedly connected to the inner walls of each connecting frame 3 and the inner wall of the tube furnace main body 1. The controller 2 is electrically connected to the tube furnace main body 1 through a wire. One side surfaces of the two connecting frames 3 close to each other are respectively in contact with the two side surfaces of the tube furnace main body 1. Two handle supports 13 are fixedly connected to the upper surface of the tube furnace main body 1, and a pull rod 14 is fixedly connected to the inner wall of each handle support 13. By providing the pull rod 14, a rotation base surface can be provided for the hand-held structure in the handle support 13, thereby increasing the flexibility of use of this hand-held structure. By providing the handle support 13 and the pull rod 14, they can cooperate with the above-mentioned hand-held structure to lift and carry the entire tube furnace main body 1 together.

[0023] An extension plate 5 is slidably connected to the inside of each connecting frame 3, a hand-tightening bolt 7 is threadedly connected to the inner wall of each connecting frame 3, and one end of each hand-tightening bolt 7 close to the extension plate 5 is in contact with the front surface of the extension plate 5. A grip 15 is arranged inside each handle support 13, and the inner wall of each grip 15 is rotatably connected to the outer surface of the pull rod 14. By providing the grip 15, it can rotate around the outer surface of the pull rod 14 inside the handle support 13, so as to facilitate lifting and carrying the entire tube furnace main body 1 after holding the grip 15.

[0024] T-shaped brackets 6 are fixedly connected to the one side surfaces of the two extension plates 5 away from each other. A clamping plate 8 is arranged inside each T-shaped bracket 6, and the bottom surface of each clamping plate 8 is in contact with the inner bottom wall of the T-shaped bracket 6. A washer 16 is sleeved on the outer surface of each fastening bolt 4, and the outer surface of each washer 16 is in contact with the outer surface of the connecting frame 3. By providing the washer 16, it can be padded between the connecting frame 3 and the fastening bolt 4, thereby increasing the contact area between the two, and thus increasing the fastening effect of the fastening bolt 4.

[0025] A sliding rod 9 is slidably connected to the inside of each T-shaped bracket 6, a push plate 10 is fixedly connected to one end of each sliding rod 9 away from the sliding rod 9, an anti-slip pad 17 is fixedly connected to the front surface of each push plate 10, and a number of identical anti-slip convex discs 18 are fixedly connected to the front surface of each anti-slip pad 17. By providing the anti-slip convex discs 18, the anti-slip property of the outer surface of the anti-slip pad 17 can be increased. By providing the anti-slip pad 17 and the anti-slip convex discs 18, the anti-slip property of the front surface of the push plate 10 can be jointly increased, so that the hand is more stable when the finger presses and pushes the push plate 10.

[0026] A return spring 11 is sleeved on the outer surface of each sliding rod 9. High-temperature anti-slip plates 12 are fixedly connected to the front surfaces of the two clamping plates 8 and the inner walls of the two T-shaped brackets 6. The two ends of each return spring 11 are respectively in contact with the front surface of the T-shaped bracket 6 and the back surface of the push plate 10. A limit slider 19 is fixedly connected to the bottom surface of each clamping plate 8. The outer surface of each limit slider 19 is slidably connected to the inside of the T-shaped bracket 6. By providing the limit slider 19, it can slide inside the T-shaped bracket 6, thereby increasing the stability when the clamping plate 8 moves relative to the T-shaped bracket 6.

[0027] The working principle of the present utility model is as follows: When in use, the connecting frame 3 is installed below the tubular furnaces on both sides of the tubular furnace main body 1 with the fastening bolts 4. Then, the tubular container or guide to be heated is inserted into the tubular furnaces on both sides of the tubular furnace main body 1. Next, according to the position of the placed tubular container or guide relative to the tubular furnaces on both sides of the tubular furnace main body 1, the relative position of the extension plate 5 sliding in the connecting frame 3 is adjusted until the T-shaped bracket 6 and the clamping plate 8 can better clamp the tubular container or guide. Finally, turn the hand-tightening tightening bolt 7 and tighten the extension plate 5 to fix the position of the extension plate 5 in the connecting frame 3. When it is necessary to use the T-shaped bracket 6 and the clamping plate 8 to clamp the tubular container or guide, hold the T-shaped bracket 6 and press the anti-slip pad 17 and the anti-slip convex disc 18 on the front surface of the push plate 10. The clamping plate 8 slides along with the sliding of the sliding rod 9 in the T-shaped bracket 6. Then, with the help of the rebound of the return spring 11 and the anti-slip assistance of the high-temperature anti-slip plate 12, the clamping plate 8 and the T-shaped bracket 6 cooperate to clamp and fix the tubular container or guide inserted at the tubular furnace opening of the tubular furnace main body 1, playing a role in increasing the stability of the tubular container or guide at the tubular furnace opening of the tubular furnace main body 1. The design of the entire high-temperature combustion tubular furnace effectively solves the problem that the tubular container or guide at the tubular furnace opening of the tubular furnace is prone to tilt or be pulled accidentally due to the lack of a reinforcing and stabilizing structure for fixing the external tubular container or guide, resulting in the tubular container or guide being easily detached from the tubular furnace and thus being prone to falling and breaking.
